Sedimentologically, the core is characterized by alternating intervals of fine-grained massive intervals (70 % ), laminated intervals (23 % ), turbidites (5 % ) and graded silt–clay layers (2 % ). The laminated intervals are comprised of couplets that vary between light-coloured, diatom-rich layers, deposited primarily during the summer months, and dark-coloured, mineral-rich layers deposited during winter. Laminated couplets are most common in portions of the core deposited between 3150 and 2700 yr BP, which corresponds to an episode of regional neoglaciation.
Time-series analysis was carried out on high-resolution particle size measurements obtained from core sub-samples and on sediment grey-scale colour variability derived from X-ray scans of the core. Non-linear time-series analyses revealed that the succession of massive and laminated sedimentation displayed characteristics of self-organization following a power law relationship for core length segments of < 13 cm (< 50 years of deposition). Wavelet and spectral time-series analysis indicated that core length segments of > 13 cm (> 50 years of deposition) contained evidence of sedimentary depositional cycles of 70–96, 135–155 and 250–330 years that reflect changes in AL and NPH mediated regional precipitation patterns that can in turn be related to larger-scale climate drivers such as the Pacific Decadal Oscillation (PDO) or solar irradiance cyclicity.
